Synthesis of quinozoline and its imino sugars by using NaY zeolite catalyst under microwave condition


3-Amino-2-phenylquinazolin-4(3H)-one 2 has been synthesized by the treatment of hydrazine hydrate with 2-phenyl-4H-3,1-benzoxazin-4-one 1 using NaY zeolite as a solid support under microwave irradiation. Compound 2 on reaction with various aldoses afforded the corresponding imino sugars 3a-h. Synthesized compounds were characterized by spectral and analytical data.

An efficient one-pot synthesis of isoxazolyl polyhydroquinolines via Hantzsch condensation using l-proline as catalyst


L-Proline is employed as an efficient organo catalyst for the one-pot, four component Hantzsch reaction for the synthesis of isoxazolyl polyhydroquinoline derivatives. This method is environmentally benign, affords excellent yields and has operational simplicity and isoxazole amines are used for the first time in this synthesis.
